To all whom it may concern: I, h

Be it known that I, ALBERT F. STONE, a citizen of the United States,residing at Montclair, in the county of Essex and State of-New Jersey,have invented certain new and useful Improvements in Carton-Cases forCollapsible Tubes, of which the follow- This invention relates tocollapsible cartons or casings forming an outer covering for collapsibletubes containing pastes, creams and other semi-liquid or liquid contentsadapted. to be expelled by squeezing the tube. l

. The object of my invention is to provide a casing or carton, whichmaybemade of cardboard or other suitable *material, and

which incloses the collapsible tube, permitting the continued use of thetube contents while preserving the shape and contour of the carton orcover.

The cover is preferably constructed of a single blank of sheet material,cut into the shape substantially as shown, and adapted to be folded onthe lines indicated.

In the accompanying drawings forming a part of the specification, Figure1 is a plan view of the blank showing the outline and the crease linesupon which it is folded; Fig. I

2, is a perspective view showing the carton partly folded and the mannerof placing the collapsible-tube in position therein; Fig. 3, is aperspective view showing the carton folded but with the top member swungback to expose the side flaps; Fig. 4, is a perspective view of thefolded carton with the bottom clamp ready to be secured; Fig. 5, is aperspective of thecarton with an inclosed, tube, and partly broken awayto show how the contents ofthe tube are expelled by pressing the cartonbetween the fingers; Fig.j 6, is a plan view ofa blank part y brokenaway, showing a slightly modified carton construction; Fig. 7, 1s adetail view of the bottom end of the latter form; Fig. 8, is a sectionalviewbn the line 8-8 of Fig. 5, and 9, is a cross-section on the line 9-9of F1%. 7. s] he carton blank is cut preferabl from card-board orfiber-board and crease in the manner illustrated in Fig. 1, andcomprises top and bottom 2, and 4, respectively, end 3, with its flaps3", 3", and sides 6 and 7 with -'th'eir flaps. 6 and 7. The top andbottom members, 2 and 4, constituting the face members of the wedge, andthe end member 8,

cated in Fig. 7.

forming the base-of the wedge, are rectangular, while the sides aretriangular, so that the folded carton is wedge-shape. I The lines a, b,and c, d, are lines' of fold between the sides and'the flaps while thelines a, e, and c, f, are crease lines extending'longitudinally upon amedian line through the sides and formed in the blank. The end flaps 3 3are also creased on a median line as indicated in broken lines. The endor base member 3 is provided with a central aperture 9 through which theneck of the collapsible tube may protrude.

When it is desired to incase'the collapsible tube in the carton, the endor base member 3,

tion as indicated in Fig. 2, with the neck protruding throughjtheaperture 9. The end flaps are then bent inwardly and'the sides andtheirflaps are folded over in the manner indicated in Fig. 3; after which thetop face member 2 is folded down over the side flaps, thereby formingthe wedge-shape casing shown in Fig.4. A suitable metal clip 12, may beplaced over the apex end and fastened by a'sealing machine to clamp theparts together. The edges a, g, and c, b, of the side flaps may be cutsubstantially square, as shown in Figs. 1, 2 and 3, so-that they willextend under the clamps 12 and be permanently secured thereby as shownin Fig. 8, or they maybe cut away at'an-angle along the lines a, g andc, h, as indicated in Figs. 6 and 7,s0 that the flaps will be free fromthe clamps as indicated in Fig. 9; In the latter case, the clamps12 willonly"fas'- ten together the ,top and bottom or face members 2 and '4 ofthe wedge, as shown in Fig. 7, and the sideflaps may'be'folded over andinserted afterward if-preferrd'and the sides 6 and 7 being thus free","=may be opened out at any time to exposethe tube as indi- As previouslystated, the neck. 14 of the tube protrudes through the aperture in theend member, as shown in Fig.5. so that the "is. bent up perpendicular tothe bottom face fme'm'ber 4, and the tube 10, is placed in posiecap 15may be removed and the contents expelled, as at 16, by pressure of thefingers upon the carton in the manner indicated in Fig. 5. In saidfigure the'earton is broken away to show how the tube within is squeezedby the pressure up'on'the carton. The sides of the carton yield underpressure and bow or bulgeoutwardly along the crease lines a, e and 0,at, this result being the function of these crease lines. The end orbase 3, however, is uncreased so that it maintains its shape due to therigidity of the card-board. When the contents of the tube have beennearly all expelled, so that it is necessary to press the carton nearthe larger end, the end flaps 3, 3", also bulge or bow outwardly alongthe crease lines with the sides.

The advantages to be derived from the use of my invention will beappreciated .from the above description. The carton maintains itsoriginal shape, due to the stifiness or rigidity of the card-board orfiber-board, and yet permits the contents of the tube to be expelled inthe usual manner by progressively pressing from the closed end toward-the discharge end or neck on account of the crease lines in the edgemembers. 7. The neat appearance of the package is, therefore, preservedduring the entire period of use and the unsightly appearance of thewrinkled and distorted partly collapsed tube is concealed. The faces ofthe carton may receive printed matter such as advertisements and labelsdescribing the contents and directions for its use, making itunnecessary to place the same upon the tube and these matters arepreserved intact throughout the use of the contents, which is animportant advantage. may also be varnished or otherwise made durable andwater-proof.

\Vhile I have described in detail the particular constructionillustrated in the accompanying drawings for the purpose of disclosingan embodiment of my invention, I am aware that various changes may bemade therein within the scope of the appended claims and withoutdeparting from the spirit of my invention.

I claim 1. A carton casing or cover for collapsible tubes, comprising afiber-board blank folded into a wedge-shaped box and having its edgemembers provided with longitudinal crease lines upon which said membersmay fold when pressure is exerted u on the faces of the wedge, while itsend or ase member maintains its shape due to its stifi'ness or rigidity.

2. A carton casing or cover for collapsible The surface of the cartonvhaving longitudinal aaeaoei tubes, comprising a fiber-board blank foldedinto a wedge-shaped box and having side, edge and base members, saidedge members being provided with longitudinal crease lines upon whichthey may fold when pressure is exerted upon the faces of the wedge, therigidity of the base member maintaining its shape and being providedwith an apgrture to receive the neck of a collapsible tu e.

3. A carton casing or cover for collapsible tubes, comprising a fiberboard blank foldable into a wedge-shaped box, said blank havingrectangular portions adapted to form the opposite face members of thewedge, an intermediate portion having an aperture to receive the neck ofa collapsible tube and connected by folding joints with said rectangularportions, and triangular portions having outer marginal flaps and unitedat their inner longitudinal edges by folding joints with the oppositeedges of one of said rectangular portions, said intermediate portionbeing sufliciently rigid to prevent distortion when the triangularportions are collapsed by pressure on the face members.

4. A carton casing or cover for collapsible tubes, comprising a blankfoldable into a wedge-shaped box, said blank having rectangular portionsadapted to form the 0pposite face members of the wedge, an intermediaterectangular portion having an aperture to receive the neck of acollapsible tube and connected by folding joints upon opposite sideswith said rectangular portions and having flaps united to the otheropposite sides, and triangular portions having outer marginal flaps andunited at their inner longitudinal edges by folding joints with theopposite edges of one of said rectangular portions, said triangularportions crease lines causing the triangular portions to bulge outwardlywhen pressure is applied to the outer margins thereof.

In testimony whereof I afix my signature in presence of two witnesses.

ALBERT F. STONE.
